3.2 Continued

Switch 1

Must OPEN

 the primary operator’s gate upon initial AC power up and open command. If the 

FIRST

 open command 

begins to close the gate, turn AC power off and reverse this switch. 

Switch 2

Must OPEN

 the secondary operator’s gate upon initial AC power up and open command. If the 

FIRST

 open command 

begins to close the gate, turn AC power off and reverse this switch. This switch will be set the opposite of switch 1 (e.g. If 
switch 1 is OFF, then switch 2 will be ON). 

Switch 3

 Determines that a device wired to terminal #4 is a normal full open command 

OR

 terminal #4 becomes the output 

from the exit loop detector that is plugged into the EXIT Loop port in the circuit board (Used for specialized functions). 

Switch 4

 Turns the auto-close timer on or off. Maximum time that the close timer can be set for is approximately 23 seconds. 

Switch 5

OFF 

setting is Standard Reverse for a 

CLOSING

 gate. An input to terminal #6 (e.g.: photo beam gets obstructed) 

AND/OR

 reverse loops will stop and 

reverse

 the gate back to the full open position. If the auto-close timer is ON, when gate 

reaches the open position, timer 

will not

 close the gate. Another input command is needed to reset and close the gate.

DO Not

 use the 

ON

 setting for the 6550 operator.

Switch 6

 Sets up the circuit board for a single gate operator or primary / secondary (dual) gate operators. 

Switches 7-8

 These work in conjunction with each other and determine when the relay on the board will be activated. This relay 

can be used as a switch for various functions such as illuminating a warning light when the gate is moving, or turning on a 
green light when the gate is full open. This relay is not available for these uses if it is being used for the shadow loop function.

Switch Definitions

Switch 1

 When the gate overlap is 

OFF

, the gate operator(s) will start the open and close cycles at the 

same time

. This is the 

normal setting for a 

single

 gate operator.

Turning the gate overlap 

ON

 when using dual gate operators will cause the secondary operator to start the 

open

 cycle 1.5 

seconds 

before

 the primary operator. The primary operator will start the 

close

 cycle 1.5 seconds 

before

 the secondary opera-

tor.

Switch 2

 If a magnetic lock is not used with the gate operator, leave this switch in the OFF position. Turn this switch ON if a 

magnetic lock is used and connected to terminals 9 and 12. This applies magnetic lock power and logic to these terminals (NC).

Switch 3

 MUST be turned OFF for the Model 6550.

Switch 4

 MUST be turned OFF for the Model 6550.
